Explanation of the trade: So I wanted to buy 500b SPK. I offered him 109M 07 for it. We both accepted the price.
Amount scammed: 54.5M
How they scammed: So he told me he'd give me 250b first, then another 250b on another account. He did give me the 250b but then never showed up again.
Proof that it's their Discord:

Discord ID + Unique Discord ID: I don't know his discord unique ID, but I've bought more from him.

@monliza2017
Can you kindly pay the remainder

 

still hasnt paid out anything yet @Gladiator

 

Hello gladitor i can proived a proof he getting me a banned and he was talked with staff about me to banned me

 

and he got his payment already if you seen his name editon already

 

im not risking any banned myself, so do not have to pay him back

 

So none of that is true, but what is true is that he got banned. Wasn't my fault though, I buy SPK from a lot of people. And none of them got banned. Anyways, @monliza2017 has paid the remainder.

 

Great, thank you @monliza2017
